ABSTRACT
Gastro-oesophageal reflux disease (GERD) is associated with substantial morbidity in patients with systemic sclerosis. Although the introduction of proton pump inhibitors (PPIs) into clinical care represents a major achievement in the management of gastro-oesophageal problems in systemic sclerosis, PPIs are seldom fully effective in patients with systemic sclerosis, and the use of maximum PPI doses is a very frequent clinical practice. However, there is little evidence to support the empirical use of PPIs in systemic sclerosis. This scarcity of evidence is especially relevant with regards to the safety concerns of long-term exposure, which have been raised in the general population. The purpose of this Viewpoint is to highlight the substantial beneficial impact of PPIs on GERD in patients with systemic sclerosis, while considering the potential adverse effects in this patient population. Furthermore, we highlight the unmet needs of people with systemic sclerosis and GERD and propose an agenda for future research to optimise the safe and effective use of PPIs in systemic sclerosis.
